You can see photographs of all the samples displayed in a periodic table format: my pictures or their pictures. Or you can see both side-by-side with bigger pictures in numerical order. The picture on the left was taken by me. Here is the company's version (there is some variation ...
In any case, my primary reason for buying this (not cheap) coin was to use a photograph of it in a periodic table poster. Bizarrely, it's cheaper to buy a stunning 2,267 year old pure silver coin than it is to license a photograph of one, plus you get to keep the coin. Look ...
One reason the periodic table of the elements is so useful is that it is a means of arranging elements according to their similar properties. This is what is meant by periodicity orperiodic table trends. There are multiple ways of grouping the elements, but they are commonly divided into meta...
